Keep It Focused
Aim for 10-25 lines of code per image. Too much code overwhelms the viewer; too little lacks context. One function, one concept, one image.
Match Your Brand
Use the custom gradient builder to create backgrounds that align with your brand colors. Consistency across your blog posts and social media builds recognition.
Always Export @2x
Most modern displays are HiDPI. A 2x export ensures your code stays sharp when viewed on phones, tablets, and retina laptops. The file size increase is minimal.
